Embodiment 1

[0042] A preparation process of the bimetallic band saw blade of this embodiment comprises the following steps:

[0043] S110, processing the high-speed steel tooth material into columnar particles through wire cutting, pressure punching and shearing, and grinding machine in sequence.

[0044] S120. Perform the heat treatment on the columnar particles as follows: heat the columnar particles to 1200° C., keep the temperature for 10 minutes, and then keep the temperature at 500° C. for 3 hours after cooling. Then put the heat-treated columnar particles in an alkaline solution to remove surface grease, and then wash them with water; then place them in concentrated hydrochloric acid and concentrated nitric acid with a volume ratio of 3:1 to remove metal oxides on the surface of the columnar particles, and wash them with water. Wash with water.

[0045] S130, placing the cationic surfactant solution and the columnar particles in the electrophoresis tank, applying a positive potent...

Abstract

The invention discloses a preparation process of a bimetal band saw blade. The process comprises the following steps: processing a high-speed steel tooth material into columnar particles, carrying outheat treatment, and cationizing the surfaces of the columnar particles to form a layer of film with positive charges on the surfaces of the columnar particles; processing a spring steel backing material into a steel belt, carrying out heat treatment, depositing a layer of nickel-cobalt alloy on one side, facing a toothed material, of each of the front and back surfaces of the steel belt by a composite electroplating method, and solidifying the surface cationized columnar particles on the nickel-cobalt alloy layers; and grinding the columnar particles to form a tooth-shaped cutting edge. The process can remarkably improve the utilization rate of the toothed material and improve the forming efficiency of a band saw.

Description

technical field [0001] The invention relates to the technical field of band saw preparation, in particular to a preparation process of a bimetallic band saw blade. Background technique [0002] As the main method of metal cutting, band saws, especially bimetal band saws, have been widely used in various industries of metal processing. There are two traditional manufacturing methods for bimetallic band saw blades: one is to weld high-speed steel wires and spring steel strips by means of electron beam welding or laser welding to form bimetallic composite steel strips, and then perform annealing heat treatment on the composite steel strips, and then select Specific milling and / or grinding tools to shape the tip of the HSS wire to the desired tip shape. The other is to process tooth holders on one side of the spring steel strip first, and then insert and weld cemented carbide particles on the tooth holders of the spring steel belt one by one, and process the tooth profile on th...
